First, three-way threaded electric ball valve overview
The three-way threaded electric ball valve produced by Shanghai Zhongmei Valve is composed of a quarter-turn electric actuator and an internal thread three-way ball valve. It is a rotary type cutting and regulating valve. It has the advantages of tight shut-off, compact structure, light weight and convenient maintenance. . The internal thread electric three-way ball valve uses 220V single-phase AC power as the power source, accepts the switching signal of the control system, and drives the reversible single-phase gear reducer through the single-phase power supply switching, so that the ball valve can switch the pipeline according to the specified requirements. The two-seat sealed electric three-way internal thread ball valve has a compact structure, beautiful appearance and good sealing performance. It can realize the switching of the medium flow direction in the pipeline, and can also connect or close two channels perpendicular to each other. The four-seat sealed internal thread electric three-way ball valve has beautiful appearance and compact structure. It can not only realize the switching of the flow direction of the medium, but also make the three channels communicate with each other. At present, it can also close any channel and connect the other two channels to flexibly control the confluence or splitting of the medium in the pipeline. The electric three-way internal thread ball valve is suitable for switching the medium flow direction and diverting or mixing the medium in the water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel and other pipeline systems.

Third, three-way threaded electric ball valve main features
1. Compact structure, rapid opening and closing, smooth flow path and low fluid resistance.
2, good sealing performance: the use of four-sided valve seat material PTFE elastic deformation to achieve a leak-free seal.
3, a multi-purpose valve: any port can be used as an inlet without leakage, the three-way can be made into an L-shaped port, or can be made into a T-shaped port.
4. Convenient maintenance: After the system is relieved of pressure, it can be inspected and repaired without removing the entire valve body.
